Hamburger, Germany
When something tastes so good that people spend US$20 billion each year in a single restaurant chain devoted to it, you know it has to fit into this list. McDonald's may not offer the best burgers, but that's the point -- it doesn't have to.
The bread-meat-salad combination is so good that entire countries have ravaged their eco-systems just to produce more cows.
Peking duck, China
The maltose-syrup glaze coating the skin is the secret. Slow roasted in an oven, the crispy, syrup-coated skin is so good that authentic eateries will serve more skin than meat, and bring it with pancakes, onions and hoisin or sweet bean sauce.
Other than flying or floating, this is the only way you want your duck.
